Installation with focus on Security (TEMPEST)

Installation related measures are important to preven coupling of classified information from equipment handling unprotected classified information to other equipment/cables that could bring the information to other organizations. This is relevant for military applications, but also when e.g. government offices and hospitals want to prevent sensitive information from being readable for other than approved personnel.

Many of the measures to prevent unwanted coupling of electrical signals are the same as used for EMI control (to achieve EMC).
